Bio-inspired smart PET bottle design for efficient evacuation of viscous condiments
Bio-inspired PET bottle design that uses hydrophobic and oleophobic micro-textures and smart surface coatings to achieve over 95% evacuation of viscous condiments. The approach reduces product adhesion to improve flow efficiency and minimize food waste without changing condiment formulations. It is intended to be compatible with existing manufacturing processes while maintaining bottle clarity, strength, and recyclability and meeting food safety requirements.
Overview
This solution introduces a novel PET bottle design that significantly reduces food waste by ensuring over 95% evacuation of viscous condiments. Inspired by natural low-adhesion surfaces like lotus leaves, the design incorporates advanced surface morphology and smart coating technologies. These features minimize product adhesion, thereby enhancing flow efficiency and improving end-user satisfaction. The solution targets improved product evacuation without altering condiment formulations.
Technical specifications
Key features include:
- Integration of bio-inspired hydrophobic and oleophobic micro-textures on PET surfaces.
- Use of scalable coating or in-mold patterning methods compatible with existing manufacturing processes.
- Maintenance of bottle clarity, strength, and recyclability.
- Enhanced geometric flow channels to reduce frictional resistance and improve evacuation efficiency.
- Compliance with food safety standards.
The design is intended to integrate into current production lines, providing a practical and sustainable approach to smart PET packaging.
Technology readiness level
Currently, the technology is at TRL 2, with ongoing development and validation planned in three phases. Phase 1 involves laboratory prototype development, Phase 2 focuses on product flow and adhesion testing, and Phase 3 aims at optimizing recyclability and conducting pilot-scale production.
